SiteOrigin not accepting text updates

I am trying to make text updates on my site. Two things happening.
a) not able to see “SiteOrigin” plugin (just the standard WP visual editor, without the visual/html options)
b) I am changing text in “visual editor” with Black Studio TinyMCE Widget it does not save the text.

I have also tried using the SiteOrigin “Editor” and it does not work.
